Löjtnant ( in the Swedish Army/Air Force, Sub-lieutenant in the Navy) is a company grade officer rank. In the army/airforce, it ranks above second lieutenant and below captain. In the navy, it ranks above acting sub-lieutenant and below lieutenant. It is equivalent to the specialist officers rank of förvaltare. The rank has been used in Sweden since the Middle Ages. Army/Air Force/Navy Löjtnant (lieutenant) is a rank in the Swedish Army, Swedish Air Force and in the Swedish Navy (Coastal Artillery 1902–2000, Amphibious Corps 2000–present). History The rank of löjtnant (lieutenant) appears for the first time during the latter part of the Middle Ages. Originally, it designated the (commander's) deputy, of which the compositions were lieutenant general, lieutenant colonel and captain lieutenant, and sometimes also the lowest commander's deputy. Eventually the word changed to refer exclusively to the company commander's deputy, and even later the rank fänrik (or cornet) for the lowest officer rank was replaced by lieutenant, after which the rank of lieutenant in Sweden was divided into two, löjtnant and underlöjtnant. The fänrik rank was reintroduced in 1914 with the same status as underlöjtnant, but it was subsequently moved one level below underlöjtnant in 1926. Underlöjtnant was removed from the Swedish Armed Forces rank structure in 1937. Duties A lieutenant in the army serves in two areas, as commander and as a staff officer in a battalion (or brigade). As a commander, a lieutenant mainly serves as a platoon leader both in the war organization and in basic training of units. A lieutenant can also be developed by serving as a teacher at a school. A lieutenant should be able to work as a “first-line commander”, to be able to lead education, practice and training and to be able to supervise colleagues within one's own area of competence. The army emphasizes that the lieutenant must be competent in supervising younger colleagues and lead platoon combat training.
